Earth Day is an annual event celebrated to demonstrate support for environmental
protection and promotion of harmony with nature. It is celebrated on April 22
(starting from 1970) although many countries celebrate Earth Day around the time
of the March Equinox (the date on which night and day are of equal duration,
usually 21 or 22 March). Also in 2009 a global International Mother Earth Day
was proclaimed by the General Assembly of the United Nations to be celebrated
annually on April 22.

Earth Day is an excellent opportunity to organize outdoor pro-ecological
activities including picking up trash and planting trees. Earth Day is also a
chance to increase awareness about the effects of environmental degradation,
including pollution and global warming, and to promote the importance of
pro-ecological endeavos, including ecologically friendly agriculture,
wastewater treatment projects.
